After you try 1 <red shift> P/YR, try to validate the entry by pressing:
<red shift> C ALL
The display should briefly show "1 P_Yr", then 0.00 (with your current display setting)
A second way to check the setting is to try:
RCL <red shift> P/YR
The display should now show 1.00
If all else fails, as a last resort you could always try resetting the calculator by doing the following:
1) Press and hold the ON key
2) While still holding the ON button, press and hold the N key
3) While still holding both of the above buttons, press the FV key
4) Release all of the keys
If successful, you should briefly see a copyright message, then "ALL CLEAr"
If there's a problem with your keys working, you can test them by running the keyboard test:
1) Press and hold ON
2) Press and release PMT
3) Release ON, display should now show "1 ScrEEn"
4) Press +, display should now show "2 kEyboArd"
5) Press =, display should now show "PrESS kEyS"
6) Press each key one after the other, starting at the top left and moving left-to-right on each subsequent row
7) After pressing the final key (+), the display should now show "Good". Anything else in the display indicates that a key was missed or didn't respond.
😎 Press C to return to normal operation.

Fourth row down, second key from left. Labeled "RCL". It recalls the value of the next key (or shifted key) you press. It's a good way to see the contents of any of the normal or designated registers if you're ever in doubt of what's currently in them.

Please note that the [×P/YR] key is different from the [P/YR] key. The [×P/YR] key (which is the shifted N key) multiplies your input by the current value of P/YR and stores the result into N. That's not what you want. The [P/YR] key (which is the shifted PMT key) stores your input directly into P/YR. That's what you want here.
